Detailed Description
Hereinafter, embodiments of the present invention are described with reference to the drawings. The following detailed description and drawings are illustrative of the principles of the invention, which is not limited to the preferred embodiments described, but is defined by the claims. The invention will now be described in detail with reference to exemplary embodiments thereof, some of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings, in which like reference numerals refer to the same or similar elements in different drawings unless otherwise indicated. The aspects described in the following exemplary embodiments do not represent all aspects of the present invention. Rather, these aspects are merely exemplary of the systems and methods according to the various aspects of the present invention as recited in the appended claims.
FIG. 1 is a perspective view of a plain bearing according to the present invention in which radial contraction of the plain bearing has been accomplished using a radial contraction assembly, the plain bearing being in a radially contracted state. Fig. 2 shows the plain bearing 1 from fig. 1 in a sectional view. As shown in fig. 1 and 2, the sliding bearing 1 includes an elastic outer ring 2 and a rigid inner ring 3. The elastic outer ring 2 may comprise rubber. The rigid inner ring 3 may comprise a material having wear, high temperature, corrosion resistant properties, such as polyetheretherketone, polyimide, ceramic, graphite, etc. The specific materials of the elastic outer ring 2 and the rigid inner ring 3 can be selected according to actual requirements. The elastic outer ring 2 comprises an annular groove 4 and a notch 5, wherein the annular groove 4 is located on the radial outer surface of the elastic outer ring 2, and the notch 5 extends from one axial end surface of the elastic outer ring 2 along the axial direction and is communicated with the annular groove 4. By means of the elastic deformation of the elastic outer ring 2, the rigid inner ring 3 can be pressed into the elastic outer ring 2 and tightly pressed against the radial inner surface of the elastic outer ring 2, and the rigid inner ring 3 can carry the rotating shaft.
According to an embodiment of the present invention, the radial contraction assembly preferably includes a band 7, the band 7 includes two connection portions at both circumferential end portions thereof, respectively, and a radial thickness of the band 7 is smaller than a radial depth of the annular groove 4.
When the slide bearing 1 is mounted, the clips 7 are inserted into the annular groove 4 to circumferentially surround the elastic outer ring 2. When the collar 7 is placed in the annular groove 4 and is forced to stretch in the circumferential direction, for example, by applying a circumferential tightening force to the collar 7 using a pipe vise or a pipe clamp, etc., the collar 7 applies a radial tightening force to the sliding bearing 1, so that the elastic outer ring 2 contracts radially. The two connecting portions of the locking clip 7 are able to hold the resilient outer ring 2 in a radially contracted state. At this time, the outer diameter of the elastic outer ring 2 is smaller than the inner diameter of the bearing housing or sleeve or the like to be mounted, so that the sliding bearing 1 can be placed in a predetermined mounting position in the bearing housing or sleeve with a clearance fit. In the case where the sliding bearing 1 is not subjected to the radial force of the bearing seat or the sleeve, the inclination of the sliding bearing 1 can be effectively reduced, and the sliding bearing 1 can be easily and accurately moved to a predetermined axial position. After the sliding bearing 1 is placed at a predetermined installation position, for example, a predetermined installation position in a bearing seat or a sleeve, the two connection portions of the locking clip 7 are released through the cut 5, so that the elastic outer ring 2 can radially expand, an interference fit between the elastic outer ring 2 and the bearing seat or the sleeve is realized, and the axial positioning of the sliding bearing is completed.
According to an embodiment of the invention, the clamp 7 may be of the form shown in fig. 1 and 2, the two connection portions of which each comprise a connection hole. The connection holes are configured such that the two connection portions of the yoke 7 can be locked to each other by passing the pins 8 through the connection holes aligned with each other. Preferably, the connection hole is provided to extend in the axial direction. The elastic outer ring 2 can be held in a radially contracted state by inserting the pins 8 into the connection holes aligned with each other to lock the two connection portions of the yoke 7. With the elastic outer ring 2 in the radially contracted state, after the slide bearing 1 is placed in a predetermined mounting position, the two connecting portions of the lock clip 7 can be released by pulling out the pin 8 from the connecting hole through the notch 5. In this case, the radial retraction assembly includes a clip and a pin.
Preferably, the radial contraction assembly may further include a wire capable of being connected with the pin 8, and after the sliding bearing 1 is placed at a predetermined installation position, the pin 8 may be pulled out of the connection hole through the slit 5 using the wire, thereby releasing the two connection portions of the locking clip 7, which is very advantageous in case the sliding bearing needs to be installed in a long sleeve.
Alternatively, the two connecting portions of the clip may include a protrusion and a recess, respectively, the protrusion and the recess mating. The projection and the recess are configured such that the two connecting portions of the clip can be locked to each other by fitting the projection into the recess. In this way, the projections and recesses of the two connection portions of the clip may not be aligned with the cutouts 5 of the elastic outer ring 2, and the two connection portions of the clip may be locked simply by fitting the projections into the recesses. After the sliding bearing 1 is placed in a predetermined mounting position, the projection and the recess can be separated by the cut 5, for example, by tilting one end of the clip by the cut 5, so that the two connecting portions of the locking clip are released. In this case, the radial contraction assembly may include only the clip.
The clips described herein are not limited to the forms described above, for example, the clips may be two-piece. Alternatively, the clamp may be of a form that can be tightened with a bolt and nut connecting both ends of the clamp, or the like.
Furthermore, the radial contraction component is not limited to the form of a clip, and includes any component that has a radial contraction function, can be locked after contraction, and can be unlocked by a cutout of the elastic outer ring. For example, the radially contracting assembly may include a string having hooks at both circumferential ends, which may be unlocked by cutting the string or unhooking the hooks after the sliding bearing is placed in a predetermined installation position.
Further, the radial retraction assembly may include a lace without hooks. The locking step is accomplished by knotting the string after the radial contraction of the elastic outer ring is completed by an external force, and the unlocking step is accomplished by releasing the knot or cutting the string after the sliding bearing is placed at a predetermined installation position.
With continued reference to fig. 1, a cut 5 may be formed from one axial end face of the elastic outer race 2 through the other axial end face of the elastic outer race 2 in the axial direction. In this way, the elastic outer ring 2 is more uniformly stressed and deformed.
As shown in fig. 1, the resilient outer ring 2 may comprise a plurality of cut-outs 5. Preferably, the plurality of cut-outs 5 are evenly distributed in the circumferential direction around the central axis of the slide bearing 1. This not only makes the atress and the deformation of elasticity outer lane 2 more even, but also more is favorable to the whole radial contraction of elasticity outer lane 2.
According to an embodiment of the invention, the axial length of the rigid inner ring 3 may be less than or equal to the axial length of the resilient outer ring 2.
As shown in fig. 2, the rigid inner ring 3 includes protrusions located on a radially outer surface of the rigid inner ring 3 and extending in the entire circumferential direction, and the elastic outer ring 2 includes recesses located on a radially inner surface of the elastic outer ring 2 and extending in the entire circumferential direction, the protrusions and the recesses being matched. In this way, the rigid inner ring 3 can be easily and accurately positioned in the elastomeric outer ring 2 in the axial direction, and axial relative movements of the elastomeric outer ring 2 and the rigid inner ring 3 are effectively avoided.
As shown, the rigid inner ring 3 comprises at least one groove located on the radially inner surface of the rigid inner ring 3 and extending in the entire circumferential direction. The at least one groove can accommodate more lubricant and can accommodate particles entering the gap between the shaft and the rigid inner ring 3 to reduce wear and thus better protect the shaft and the sliding bearing. The number and arrangement of the grooves can be set according to actual needs.
According to an embodiment of the invention, the clamping band can be removed from the annular groove after the slide bearing has been mounted by means of the clamping band, for example, the clamping band can be made of a relatively soft material and therefore has a relatively good flexibility, which can be removed from the annular groove by means of its deformation through the cut-out of the spring cup.
In other embodiments, the clip cannot be removed from the annular groove after the sliding bearing is installed, for example, the clip is constructed of a rigid material. In this case, since the clip is located in the annular groove of the resilient outer ring which remains stationary relative to the apparatus to which the sliding bearing is mounted during operation, the clip remaining in the groove is normally held stationary so as not to interfere with the operation of the apparatus. The clips are not limited to any of the forms of clips described herein.
The present invention also provides a sliding bearing assembly comprising any one of the sliding bearings according to the present invention and any one of the radial contraction assemblies according to the present invention.
The present invention also discloses a method of installing a sliding bearing, which may be any of the sliding bearings described herein. The method mainly comprises the following steps.
A clamp is provided, which may be any of the clamp described herein, wherein the clamp comprises two connection portions at two circumferential ends thereof, respectively. Alternatively, the two connection portions may include connection holes, respectively. Alternatively, the two connecting portions may comprise mating projections and recesses, respectively.
Inserting a band into the annular groove to circumferentially surround the elastomeric outer ring, wherein a radial thickness of the band is less than a radial depth of the annular groove. Preferably, the clip is arranged such that the two connecting portions of the clip are at positions corresponding to the cutouts of the elastic outer ring.
And applying a circumferential tightening force to the clamp so as to stretch the clamp in the circumferential direction, thereby causing the elastic outer ring to contract in the radial direction. For example, a circumferential tightening force is applied to the clamp using a pipe vise, pipe clamp, or the like. Accordingly, the clip exerts a radial tightening force on the sliding bearing, causing the resilient outer ring to contract radially.
The two connecting portions of the clip are locked to each other so that the elastic outer ring is held in a radially contracted state, whereby the elastic outer ring can be placed in a predetermined mounting position in the bearing housing or the sleeve in a clearance-fit manner. Specifically, for example, the two connection portions of the band may respectively include connection holes provided to extend in the axial direction, and the two connection portions of the band may be locked by inserting a pin in the axial direction into the connection holes aligned with each other. Alternatively, the two connection portions of the clip may include a protrusion and a notch, respectively, and the two connection portions of the clip may be locked to each other by fitting the protrusion into the notch.
After the sliding bearing is placed at a preset installation position, the two connecting parts of the locking clamp are removed, so that the elastic outer ring can expand radially, and the interference fit between the elastic outer ring and the bearing seat or the sleeve is realized. For example, when the two connection portions of the clip include the connection holes, respectively, the two connection portions of the clip can be unlocked by pulling the pin out of the connection holes through the slits of the elastic outer ring. Preferably, the pin may be coupled with the string, in such a manner that the pin can be pulled out of the coupling hole using the string. Alternatively, when the two connection portions of the clip include the protrusion and the recess, respectively, the two connection portions of the locking clip may be released by separating the protrusion and the recess through the notch of the elastic outer ring, for example, by tilting one end of the clip so that the protrusion is separated from the recess.
While the invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the construction and methods of the embodiments described above. On the contrary, the invention is intended to cover various modifications and equivalent arrangements. In addition, while the various elements and method steps of the disclosed invention are shown in various example combinations and configurations, other combinations, including more, less or all of the elements or methods, are also within the scope of the invention.
